Method of controlling a hybrid vehicle during regenerative deceleration

摘要

A method of controlling a hybrid vehicle (1) during regenerative deceleration, the method including the steps of: determining deceleration of the vehicle (1); operating a reversible electric machine (13) as a generator to regenerate part of the kinetic energy of the vehicle (1); establishing a respective minimum speed of an internal combustion engine (5) for each gear of a servocontrolled mechanical power train (7); determining and engaging the highest gear combined with the current state of motion of the vehicle (1), runs the internal combustion engine (5) at higher than the respective minimum speed; keeping the gear engaged as long as the internal combustion engine (5) runs at higher than the respective minimum speed; and downshifting by one gear when the internal combustion engine (5) runs at lower than the respective minimum speed.
